6 Claims. l

This invention relates to a portable, sectional bulkhead.

'I'he principal object of this invention is the provision of a portable sectional bulkhead which may be prefabricated, transported by normal means of transportation to the place where the bulkhead is to be erected, and there set down and locked into place. Essentially, this inven tion contemplates a construction comprising a base, dowel anchors on said base, a wall, and reinforcing members, cast or otherwise fabricated into a single unit. The bulkhead herein claimed may be made of any desirable material or combination of materials such as concrete, reinforced concrete, or reinforced concrete and steel. Where practical and desirable, wood may be used for the purpose indicated.

A preferred embodiment of the invention is shown in the accompanying drawing in which- Fig. 1 is a perspective View, partly in section, of a bulkhead comprising a plurality of the bulkhead sections which will herein be described, these sections being shown locked together;

Fig. 2 is a fragmentary face View of the sections shown in Fig. 1 showing said sections before they are locked together;

Fig. 3 is a vertical section on the line 3 3 of Fig. 1; and

Fig. 4 is a fragmentary section on a plane transverse to the plane of the section shown in Fig. .3, showing how adjoining bulkhead sections are locked together.

As has already been indicated, the construction herein claimed comprises a base member l having a plurality of dowel anchors l l, a sloping wall I2, and a plurality of reinforcing webs I3 al1 integral therewith. It will be noted that on one side edge the wall is provided with a tongue I4 and on the opposite side edge with a groove l5. It will also be noted that the webs which extend from the top of the wall to the inner end of the base are positioned in such manner that two of them are formed on the side edges both of the wall l2 and the base Il! and that these side webs are provided with registering holes I6 adapted to accommodate bolts I1.

Fig. 1 will show that adjoining bulkhead sections are adapted to enter into tongue and groove relationship with each other thereby forming a water tight connection between them. To lock adjoining bulkhead sections together, the bolts Il are provided. Weep holes i8 are provided in the wall I2, these weep holes being formed intermediate the low and high water points at the place where the particular bulkhead is to be used.

The construction shown in Fig. 3 is of reinforced concrete. The entire section, to wit, the base, the dowels, the wall and the reinforcing webs are cast into a single unit. Mesh reinforcing members |9 are used to strengthen the structure. It will also be noted in Fig. 3 that the dowels at the front of the bulkhead are shown in solid lines whereas the dowels at the rear of the bulkhead are shown by means of dot and dash lines. The reason for this is the optional character of the rear dowels. They may be used on a soft bottom for example, but they need not be used, and of course they cannot be used on a rocky shore.

Reference again to Fig. 1 will show that the wall may be provided with a face or front portion and a side portion 2l. 'Ihe side por- 20 tion 2l serves to end 01T or close 01T the bulkhead.

In this construction, the side wall 2| not only serves as a wall but it also performs the function of one of the reinforcing webs so that in the end bulkhead section there are only two webs and one side wall, whereas in the intermediate sections there are three webs and no side walls.

It will be understood that what has been above described is but a preferred embodiment of the invention and modifications and variations may be incorporated therein without departing from the basic principles of the invention. For example, although three reinforcing webs are shown on each intermediate bulkhead section, any other number of reinforcing webs may be used depending upon the width of the bulkhead section and the water pressure it is called upon to resist. Two webs, one on each side edge of the wall and base sections would be suii'icient for each bulkhead section where the bulkhead section is relatively narrow and the water pressure relatively low. An increase in the width of the bulkhead section and an increase in the water pressure which it is required to resist will necessitate a greater number of webs, to wit, four or five or even a greater number.

I claim:

1. A bulkhead comprising a relatively narrow base adapted to cover a relatively small area, anchor dowels connected to said base, a wall on said base, and reinforcing members braced between said base and said wall, said base, dowels, wall and reinforcing members constituting a unitary construction.

2. A bulkhead section comprising a relatively narrow base adapted to cover a relatively smallv area, anchor dowels connected to said base, a wall on said base having a groove on one side edge and a tongue on the other side edge, and reinforcing members braced between said base and said wall, said base, dowels, wall and reinforcing members constituting a unitary section adapted to enter into tongue and groove relationship with other sections of the same construction.

3. A bulkhead comprising a relatively narrow base adapted to cover a relatively small area, anchor dowels connected to said base, 'a Wallon said base and reinforcing members braced between the base and the wall, said base, dowels, wall and reinforcing members being made'of reinforced concrete and constituting a unitary casting.

4. A bulkhead section comprising a relatively narrow base adapted to cover a relatively 'small area, anchor dowels connected thereto, a Wall on said base `having a groove on one side edge and a tongue on the other side edge, and reinforcing members braced between the base and the wall, said base, dowels, wall and reinforcing members being made of reinforced concrete and constituting a unitary casting adapted to enter into tongue and groove relationship with other castings of the same construction.

5. A bulkhead section comprising a relatively narrow base adapted to cover a relatively small area, anchor dowels connected thereto, a Wall on said base intermediate the ends of the base, said wall being provided with a tongue on one side edge and a groove on the other side edge, and reinforcing webs braced between said wall and said base, two of said webs being positioned at the side edges of said Wall and base and being provided with registering bolt holes, said base,

dowels, Wall and reinforcing webs constituting a unitary section adapted to enter into tongue and groove relationship with adjoining sections of the same construction and to be locked to said adjoining sections by means of bolts carried in said bolt holes.

6. A bulkhead section comprising a flat relatively narrow base adapted to cover a relatively small area, anchor dowels'con'nectedto said base, a sloping wall on said base having a tongue on one side edge and a groove on the other side edge, and reinforcing webs braced between said wall and said base extending from the top of the wall to oneendof the base, two of said webs being disposed at the sideedges of said wall and base and being provided with registering bolt holes, said base, dowels, wall and reinforcing webs being made of reinforced concrete and constituting a unitary casting adapted to enter into tongue and groove relationship with adjoining castings of the same vconstruction and to be locked th'e're'tdby means of bolts inserted through `Said b olt holes.
